skate trick also known as "pop shove-it", "pop shuv-it" or "ollie varial". consist of an 180 degrees rotation of the board under your feet by hitting the tail with the back foot and directing the skate with the front foot. Can be "backside" or "frontside" depending in wich direction the board rotates (clockwise or counterclockwise). If you make a 360 degrees rotation it will be called a "360 varial"...

Edgar Kausel is the absolute varial master... i saw him doing 3 feet ollie varials over hydrants and trash cans in the streets of Santiago...
